Weekend Reading: Mastery Learning, Burundi’s Capital, and SRTM
Khan Academy’s Andy Matuschak on tasks that require “depth of knowledge” versus those that have higher “transfer demand.” Both can be considered “difficult” in a sense, but teaching techniques to build knowledge need different approaches:
One big implication of mastery learning is that students should have as much opportunity to practice a skill as they’d like. Unlike a class that moves at a fixed pace, a struggling student should always be able to revisit prerequisites, read an alternative explanation, and try some new challenges. These systems usually consider a student to have finally “mastered” a skill when they can consistently answer related problems over an extended period of time.
It’s not every day you see the map changing:
Burundi is moving its capital from the shores of Lake Tanganyika and deep into the nation’s central highlands.
Authorities announced they would change the political capital from Bujumbura to Gitega, which is located over 100 kilometers (62 miles) to the east.
This is an awesome tool from Derek Watkins. It makes downloading SRTM data dead simple.
